Water is one of the most valuable resources on the planet. But, it is frequently exposed to bacteria as it travels along streams, tunnels through the earth to underground aquifers, or rests in lakes.
Waterborne diseases are responsible for a staggering loss of life prior to the introduction, of residential and municipal water disinfection. In many developing countries, a lack of access to safe drinking water leads to tragic, unavoidable deaths.
Due to the unrestricted entry of wastewater into the environment, and the transport of microbial contaminants to humans and organisms, environmental protection necessitates the use of appropriate purification systems, with high microbial agent removal efficiency.
Which microorganisms are present in water?
While, water can be home to a diverse range of microbiological organisms, giardia and cryptosporidium, as well as bacteria such as E. coli, shigella, and salmonella, are among the most common causes of concern.
Water can also carry viruses such as rotavirus and norovirus. Water is the universal solvent, collecting everything from dissolved salts to organic matter and mineral content, as it travels from rainwater to aquifers through the earth.
What are the WWT applications for microorganism removal?
· UV Disinfection
UV purification is one of the most popular, prevalent, and dependable methods of residential bacteria treatment.
Bacterial DNA is neutralized by ultraviolet light, preventing them from reproducing in water. This renders the bacteria harmless and prevents them from infecting you or your family. UV water purification systems produce no wastewater, require little maintenance, are extremely effective, and use no chemical additives to purify the water.
As a result, they are widely regarded as one of the most effective methods, of removing biological contaminants from water or wastewater.
Water treatment centers all over the world use chlorine to disinfect water supplies, and remove waterborne pathogens from drinking water.
Chlorine is a widely used disinfectant because it is easily added at large scales, can be precisely measured, and behaves predictably. When chlorine interacts with bacteria, it breaks down chemical bonds at the molecular level.
When chlorine is added to water, it produces a weak acid. This acid, known as hypochlorous acid, penetrates the negative charge of bacteria's cell walls, killing the organism from within. It is safe to consume in small and controlled doses. While, chlorine does leave a chemical aftertaste in water, the taste of the water can be easily improved with a carbon filter.
· Ozone Treatment
Ozone is a highly effective and one-of-a-kind water disinfectant. Ozone is extremely germicidal and destroys any waterborne viruses and bacteria, at an unrivalled rate.
Ozone, like chlorine, oxidizes bacteria and protozoa upon contact. Ozone penetrates the cell walls of microorganisms, causing structural rupture. Unlike UV disinfection, there is no need for a reduced flow rate or an extended contact time.
Ozone can also effectively eliminate inorganic matter as well as micropollutants, such as pesticides and herbicides. It has been shown to have greater disinfection capabilities than traditional chlorination, as well as the ability to disinfect water much faster than chlorine.
However, ozone is a volatile gas. It degrades in about 30 minutes, making it difficult to use for water treatment in cities.
Fears of waterborne contaminants have decreased as more people rely on water from city distributors. Private good owners and those drawing water from unsterilized sources, on the other hand, face the very real threat of bacteria residing in their water.
Bacteria and waterborne pathogens can be eliminated from water with vigilant testing and appropriate water filtration and disinfection, protecting you and your home from disease.
